.This invention vrelates to contrivances'or' devices for the purpose of removing soot from volve `a spirally disposed wire which Vis a'r-kV v ranged closelyto the inner wall of the ver tical and horizontal pipes, and thereby effectively andpositively loosen and remove all'of the sootand the like that has accumuf lated therein, and causing'the settlement in the. vertical vpipe to` fall within the stove, lwhilethat'in the horizontal pipev will be car-- ried into the flue of thechimney. Y i

As the invention after once installed, will remain permanently in the original position, the necessity of handling the pipe at any time is entirely'eliminated; which is indeed a decided advantage and the needrof vwhich has been long feltfby those whom are almost daily in contact with stoves and similar lire-` burning devices. j 1 i vl/Vhile I havey herein disclosed'one precise embodiment of my invention, it is therefore subject to certain minor changes in the details of construction, in the event thatthe samewould become necessary in the practical development of` the device forfthe market. However, in such an event the general principle as hereinafter described v and later F claimed, will not of coursev become thereby' affected. l i' TheY accompanying drawings form an important part of this illustrationgpand the numerals thereinl correspond to similar ones inv the .following detailed description: and, Figure-.1 is areduced'view of the complete devicf-i asvl itis applied to the vertical and horiZonal stove-pipes partial view of the flue being in section; also '4f a portion of the connecting stove inplain view.

VFigure 2 is a transverse section on line ",1-1 vof Figure 8; but in an upright position.:

and said pipes and'a Figure 3 is a view taken upon the line 2--2y Figure 4 is a sectional viewupon the line 3 3 of'Figure 5. Figure 5 is an elevation taken at the line i4-l of Figure 1. 'i l Y The invention comprises properly a framei workhaving ai strip of metalindicated by the numeral 1, and which has ends 2rfformed as shown and connected to the stove'pipe by rivets 3 which pass through holes in the said ends'for same. `A bevel-gear lis secured to 60 horizontal shaft 5 by pin 6,v and oner end of said shaft is supported bystrip of metal 7 which is solderedto the portion lof'the framework and carries bushing Sfor said end and Cotter pinl 9 as indicated- Theop- 65 posite end' of shaft 5 rotates withinbushing V10, which is pressed into an opening forsame in the said stove-pipe, andfwhichis clearly indicated in Figure 2. It is alsonoted that the end 11 of shaft 5 is formed into a crank 70 which receives a handle portion 12. v internally threaded sleeve or coupling 13 is provided7 and is adapted to receive the eX- ternally threaded end of the shaft ,5, andaY similarly threaded end ofportionll; and the object of said coupling beingthatftheunit now being described may be placed into the stove-pipe as a whole,and the portion -11 of said lshaft drawn up into same from the .outside thereof, in the installation of the device for permanent'tuse."4 U I Y i Small bevel-gear14 is provided vand is'v secured to vertical-shaft 15 by pin', 16. With reference v`to Figure 2 it will be seen that aV 'strip of metal 17 is formed as shown 'and 85 soldered to the part 1 vofthe framework, and which has' van opening inj the top portion thereofto receive bushing 18,V and there is also a similar bushing 19 in portionl, both of whichbushings are for .the shaft 15.4

Sleeve 2O is securel'y'pre'ssed` upon the upper `end of shaft 15, and has a lateral opening therein to admit ofthe passage of one end` ofk the spirally :disposed wire 21 which wire isat tached to saidfsleeve by bending sharply, as 95` 21A. Y i Y Still referring lto Figure 21it isclearlysee'n, that by` rotating the shaft 5 by the Vha'ndle12',

- sleeve .20 V'upon the vertical 'shaft 15 will likewise'rotate and simultaneously turnthe endofj 100 PATENT orifice.

the wire 2l, and as-said wire extends through practically the entire length of the vertical stove-pipe, it is readily seen that the said pipe y will be eii'icientl-y cleaned by Vthis operation.

A particular advantage of the device is the fact that it provides a means by which the horizontal, as well as the vertical, section ofk the stove-pipe will also be cleaned in the single operation. To accomplish this a mechanical Vunit is disposed within vthe elbow of the stove-pipe, and is composed yof a strip of,

and soldered to strip 22 as indicated; `and which makeup the framework for this unit, y

A large bevel-gear upon the horizontal's'haft,

and which is clearly seen in Figures-l and 4.

Similar bevel-gears 26 and 27 are provided7 and gear 26 is secured to the vertical shaft 28 by vthe pin 29, while the gear 27 is likewise secured to'horizontal shaft 30 by pinl 3l, and

bushings 32.are mounted in strip 22, and bushings 33 in strip 25 for the aforesaid respective shafts. Y Y

" Spirally disposed wire 34 is employed to operate within'the horizontal section Of the stove-pipe, and lone end thereof'vpasses Y through aniopening insleeve 35, which -is pressed-upon shaftBO, and said wire sharply bent, as at- 34A; while sleeve 36 is likewise vconnected 'to` vertical shaft 28 and also has an opening therein to receive the end 21B of the wire 2l, and' sharply Vbent as thereby indicated. A

LFrom the foregoing description itis vnow understood that the upper and lower units are permanently connected, yand that the operation of the said lowerunit will simultaneous- 1 ly Aactuate the said upper unit, thereby effectively cleaning the vertical fandl horizontal sections of the stove-pipe, and which may be clearly interpreted by referring particularly to Figure l. 'i

A very important fact is that the entire mechanism of the device is of a very simple construction, and of the lowest'valued materialsconsistent with the requirements, and in this connection all of the Vbevel-gears indicated may be of a similar material, as the duty they are to perform does not of course necessitate a great amountrof strengthn The general framework ofV both units may be composed of a medium-light sheet metal, andv likewise' the shafts and other parts are of a simple and e low-valued material.

Having thus described my invention, what I claimas new is:

l. In a device .of the character described, a

. lower mechanical unit disposedy within a stove-pipe, said lunit comprising a frame bevel-gear secured thereto, a vertical shaft with a smaller bevel-gear secured to same, bot-h of the aforesaid gears to properly mesh,l

means upon the first-named strip to support a` lower unit secured within a stove-pipe, in-

cluding a horizontal and a verticalshaft, a

and a 'smaller bevel-gear uponthevertical shaft, said gears to mesh, and the said `shafts for same torotate in 'bearingswithin the vsaid framework; a sleevedisposed upon the upper endv of the said vertical shaft, a spirally disposed wire within the said stove-pipey and Y lmeans lconnecting the sleeve tothe end lof the said Vwire so that,` same will y rotate whenth'e said mechanism 1s actuated.

3. In a deviceof the character described, i

a lower mechanical unit disposed within a vertical stove-pipe, actuated by' aneXtern'ally arranged crank, a spirally disposed wire within the said stove-pipe, one end ofwhich is connected vto the said unit; an upper mechanical unit disposed within the elbow of the stovepipe, said unit comprisinga" metal strip with the ends thereof'formedso as to conform to the said elbow, and secured thereto, an additional metal'strip completing the framework of the said upper unit, a vertical shaft and a horizontal shaft mountedon said strips, a bevelfgear securedto eachl of the said shafts, and said gears to properly mesh; 'a sleeve diss posed upon the outer end of each of the said shafts, a spirally disposed `'wire'to operate within the horizontal section of ythe said stovepipe, and oneend thereof connected to the lsaid sle'eve of the aforesaid horizontal'shaft,l and one end of the said spiral wire'within the verticalfsection of the said stove-pipe connected tothe sleeve of the said vertical shaft, so that whenthe aforesaid lower'unit is actuated by the said external crank therefor, the said spirally disposed wire'within the verticaland horizontal sections 'of the stovepipe will simultaneously rotate within the said f p1pes,specilica1ly for the purposedis'closed. l

In testimony whereof I hereunto affix my signature. Y ,Y ,o l
